Phrenology was an early theory of psychological thought that's
basic premise was that personality could be determined by the
bumps and shape of an individual' head. Although it is no longer
accepted as valid, Franci Gall, who is considered the father of
phrenology should be given credit for propigating the believe
that the brain is the organ of all mental processes and that it's
structure will play a major role in determing behavior.
